SCREEN coivsrnucrion.

To all 'whom t may concern:

Be it known that I, WILLIAM N. Gnorrnn, a citizen of the United States, residing at Lexington, in the county of Fayette and State of Kentucky, have invented certain to` window frames, and it consists in the combinations, constructions and arrangements herein described and claimed.

. An object of my invention is to provide a screen construction which may be readily attached to a window frame, `and which,

. when so attached, may beswung to an open" position and retained in said open position.

`A :lurtherobject` of my invention is to provide a simple means of suspending the screen frame pivotally at the top so as to require only a few moments work in hangin@ the frame. y y

A further object of my invention is to provide a device of the type described in which a portion of the suspension means also serves `as an attachment for hanging the screen frame on a suitable support when the screen is put away, as for instance, dur ing the winter. y

A further object of my invention is to provide a means for pivotally securngthe screen frameto the window ame which is relatively simple; in construction, has iew` parts, and is not liable to easily get out of order. 1 i

i Othei1 objects features of the invention will be particu-` larly pointed out in the appended claims.

' y invention is illustrated in the accompanying drawings, forming part of this ap.-

plication, inwhich Figure 1 is a face view of a window frame with my improved screen construction applied thereto;

Fig. 2` is a section along the line 2-2 of Fig. 1the screen being shown in its open `struction "disclosed in the Patent `12413715, granted October 23d,`1917, to W.`

N. Croppcr and S. L. Lancaster, the present Invention relatingrmore particularly to the and advantages will apear4 in the following specification, and the novel` Specification of Letters `Patent. Patented Jane 2.4:,l Application nea March 31, `191e. serial No. 286,337. i

The present application is designed to be an lmprovement on the screen frame con- No.

manner of atta ng the screen :trame to thewindow frame creasing. 1

` Referring now particularly to Fig. 2 it `will` be seen that the screen frame proper consists ofa set Ior four channel strips 1, 2,

3 and 4t, these channelstrips having straight outer faces, a flat central portion and an inner portion bent at an angle of approximately 450 from the central or base portion. `In Fig. 2, the outer face is shown at 3% the central portion at 3b," and the inner face `at .36. A keeper 5, which is substan- 1 tially V shaped in` cross section, is disposed within the channel strip and the wire screen has 1ts edges heldbetween the keeper 5 and the inner face of thechannel strip. Toward the bottom of the screen I provide a base member which consists of a rod 6 having a head 7 ateach end thereof. The inner 1n` clined face of the channel strip, for instance `the channel strip 2 (see Figs. eland `5) is provided with an openin A bent back as shown in Fig. 4, thebrace rod is inserted in place and then these bent back `portions vare again straightened `out in the manner shown in Fig. 5y. y This leaves the head of the brace rod firmly secured between the inner filler Eiland the inclined inner face, asfor` instance the face 3b." y y p At the upper partoi' the screen Ip'rovide aplate -10 which isbent around at ,its centerto form a tube 11, the ends of the' plate being brought together and being riveted to the screen frame at 12. Within the tube 11 at each end thereof is a slidable cylindrical rod 13. The inner ends of the rod 13` are provided with set screws 14 which project through a slot 15 in the tube 11. A

`chain 16 is secured to the set screws 14.

i at 20.

yirrzrmi the Meeting description cf" the `the setv screws 14, slide the members'13 inwardly, bring them into` registration with the openings 22, then push them outwardly luntil they enterthe openings and secure the set screwsin position.y They screen frame willnthen swing on jthe ,pivot members 13. so

, i that the. screen maybe opened and held, in

the position shown in Fig. 12 by meansy oithe lrod 17 land-stop 230. yVillen it isldesired; to

remove `=the screen, 'thej'set screws 14,., are loosened, thelpivolt members13 are'withdrawn.. andthescreen frame may be imme- ,diately detached. The .chain ltwilli serve.. as -vanmeans for suspending the detached, vscreen frame, ,therebyobviatin'g the necessity ofresting the screen on the floor where it may-becomefbroken. When thescreen is suspended from the Itop in` the-manner ldescribed it maybe locked atpthe bottom, by

any.. suitable device.` such as a. hook -25 fand pin 26, thusholdingthe frame` securely in .place, but v.permitting it to be instantly 30,.

opened. inthe manner described.

I claim: 1;;In a ,screen construction, a lframe, a

,Y screen carried thereby, a plate bent at its .center to form a tube vandfliaving its ends brought togetherY and. rivetedl to they frame,

`#said-tube having a lcentral -slothon Ione. side thereof, a slidable cylindricalpivot roddis- `posedinpaeh `end .of said tube, anda Set ',sereW. carried by the inner end of each of` the pivot rods and arranged, to.y project through vvyvthe. central slot in said tube for-clamping l the rods to thetube.

" 2.1The: combination, with an outer. frame y.havingsockets, yof'a screen frame comprising a .suspension plate bent at its` center to form ya-'tu'befand having its ends brought togather, andsecured-te the screen bearingf'pori y, tion, a: slidable: cylindrical rod kdisposed atl ',Qopies eftnhjisggpafceziit may/ be' `obtainsdfor each yend of lsaid tube,y the ,endsA of thel rod gbeing .arranged yto, ,enter the, socket, and a `ing arranged to venter said sockets, a set screw secured to the inner end of each oi said rodsand arranged to pro]ect through said 'slot for securing the rod to the tube,

and a chain attached to said set screws.

4, The ycombination with an outer frame having sockets, of a screen frame, aplate secured to the upper end of said screen frame and, being looped to form a tube having; a central slotl at one side thereof, a slidable rod in each end ofvsaid tube, a set screw secured to each rod and arranged to slide in said slot for clamping the rod to lthe tube, the end of each rod being arranged to enter one of the sockets orpivotally suspending the screen, and a pivoted arm secured to the frame at one end and arranged to engage a4 portion of the outer frame at the othery end. for holding the screen yframe in an open position.

5. Thercombination with an outer frame having sockets, of a screen frame, aplate securednto the upper end offsaid screen f frame and being looped to form a tube having a4 central slot at one side thereof, aslidable rodin each end of said tube, a set screw secured to each rod and arranged to slide in said slot for clamping the rod to the tube, the end of each rod being arranged-to enter one of the socketsl for pivotally suspending the screen, a pivoted arm secured to the frame at oneend and arranged to engage a portion of theouter frame at the other end for holding the screen frame in an open position, and means at the bottom of the frame for locking the latter to the outer frame.
